Patent CA-2086279-A1 (CA)
Title: A differential detection demodulator
Inventor: KOJIMA TOSHIHARU
IPC: H03D7/16
Filed: 1992-12-24
Abstract: Within a differential detection demodulator, a received signal is first quantized by a limiter amplifier and then subjected to frequency conversion by a frequency converter including: an exclusive OR element; a running average generator consisting of a shift register and an adder; and a comparator. In response to the output of the frequency converter, the phase comparator outputs a relative phase signal representing the phase shift of the received signal after frequency conversion relative to the phase reference signal. The phase comparator includes: an exclusive OR element; an absolute phase shift measurement means consisting of an adder and D flip-flop arrays and; and a D flip-flop serving as a phase shift polarity decision means.      Alternatively, the phase detection circuit for generating the relative phase signal may include: a half-period detection means consisting of a delay element and an exclusive OR element; a phase reference signal generation means consisting of a modulo 2N counter; and a phase shift measurement means consisting of a phase inversion corrector and a D flip-flop array. The delay element delays the relative phase signal by one symbol period and the subtractor outputs the phase difference signal representing the phase transition over each symbol period of the received signal. The decision circuit obtains the demodulated data from the phase difference signal.

Title: Stress concentrator aperture-forming means for sealed containers and packages
Inventor: REDMOND SANFORD
IPC: B65D75/36
Filed: 1993-03-08
Abstract: ABSTRACT           A stress concentrator aperture-forming structure for containers or packages for flowable products, which allow controlled dispensing of the flowable products with one hand. The stress concentrator includes a substantially flat, relatively stiff sheet, one or more elongated, thin-walled, generally channel-shaped protrusion members, and a fault area crossing one or more of the protrusion members.  An enclosed pouch containing the flowable products may also be attached to the stress concentrator.  Rupturing the stress concentrator protrusion members across the fault line forms an aperture-forming pattern, which upon application of pressure to the container or package expands to form a larger aperture.          Alternate embodiments of the present invention incorporate the rupturable stress concentrator onto containers or dispenser packages for use with a wide variety of liquids. Another embodiment incorporates the stress concentrator inside a pouch having a slit opening, where upon rupturing the stress concentrator the flowable products flow through the stress concentrator and the slit opening.

Title: Callase-related dnas and their use in artificial male sterility
Inventor: SCOTT RODERICK J
IPC: C12N15/82
Filed: 1992-07-23
Abstract: A tapetum-specific callase (.beta.-1,3-glucanase) gene, designated A6, from Brassica napus and other members of the family Brassicaceae including A. thaliana has been discovered, isolated and cloned. The A6 gene encodes a 53 kDa callase enzyme of Brassica napus and equivalent proteins in other Brassicaceae family members. Coding sequence from the gene can be driven by an appropriate promoter to induce male sterility in plants.  Further, the A6 promoter can be used to drive male sterility DNA such as that coding for a nuclease, protease or glucanase.  Alternatively or in addition, male sterility can be achieved by disrupting the proper expression of the A6 gene, for example by transcribing RNA which is antisense to the RNA normally transcribed from the A6 gene, or by expressing DNA coding for a ribozyme specific for the A6 gene RNA transcript.
